SPECIFICATION forming part of Letters Patent No. 280,275, dated June 26,1883.

Application filed December 1, 1882. I'No model.) Patented in EnglandAugust 17, 1881, No. 3,582.

To all whom it may concern:

Be .it known that I, CHARLES WINN, a subject of the Queen of GreatBritain, residing at Birmingham, in-the county of Warwick, England, haveinvented certain new and useful Improvements in Water-Taste Preventersfor Flushing Water-Closets, and for like purposes, (for which I havereceived Letters Patent in Great Britain, No. 3,582, dated August 17,1831,) of which the following is a specification. This invention hasreference to improve ments in the construction of water waste preventersfor use in flushing water-closets or for other purposes.

The object of. my invention and the advantages I seek to secure therebyare to provide for a good flush while economizing water and preventingits wasteful use in flushing the pipes. is so constructed as to dispensewith valves, leathers, rubbers, or joints liable to wear away and getout of order, and the containing tank or reservoir has tapering sidesand rounded corners, so as not to be liable to fracture from frost.

The invention is illustrated in Figures 1 to 4 of the accompanyingdrawings, Figs. 1, 2, and 3 being sectional views, partly in elevation;and Fig. 4, a detail "iew in perspectii'e.

According to the arrangement illustrated in Fig. 1, I combine with orfit to a cistern, 1, of

" any desired capacity, a siphon-tube, 2, by

I surround and inclose its open legwith or by means of averticallydepending or guided cylindrical cap or cover, 3, which depends from oris connected to one end, 4, of a lever, 5, centered at 6 to an innerprojecting lug, 7, of the cistern, and to the other end, 8, of whichlever the usual draw-handle or pulling-wire, 9, is connected. When inapposition of inaction the lever 5 rests upon another lug, 16. s Theaction of this arrangementis that 'when the handle or wire 9 is pulledthe cap 3, covering the open leg of the siphon 2, is raised, and tendsto cause less than the atmospheric pressure in the space above the watertherein. The full atmospheric pressure, then acting on the water in thecistern 1, causes it in equaliz- The apparatus hereinafter described ingthe pressure to flow into the siphon, which,

being thus set in action, continues in action 'as liereinbeforementioned, and as illustrated in Fig. 1; or, for greater convenience orecontherefrom and suitably connected thereto, as illustrated in Fig.2,'so that in case of accident it can be replaced at a very small cost; orit may be made in parts, with the double bend separate from the legs,the parts being suitably connected together, and one or other of thelegs being suitably connected to the cistern. Fig. 3 represents thesiphon as arranged outside and underneath the cistern. The action in allsuch cases is similar to that. hereinbefore described.

The improvements also comprise the fitting of the cistern with animproved ball-valve apparatus for supplying the cistern with water, andwhich is so adjusted that 'water cannot enter thecistcrn until theaction of the siphon has ceased in the emptying of the cistern, norafter the latter is filled to the proper level. The combined arrangementthus constitutes a perfect water-waste preventer of a most simple andinexpensive construction. This action of the valve is eifectedautomatically, and is insured by slotting the lever 10, as shown inFigs. 3 and 4, carrying the ball or float 11 at its intersection 12 withthe cross-pins 13, proj ccting from the valve 14, so that the ends ofthe slots 12 only engage with the pins 13 of the valve at the time whenthe cistern is filled or emptied, the slots moving freely about the pinsand having no action on the valve in any intermediate position of theball-lever 10, so that the valve is closed when the cistern is quitefilled, and is not again opened (though the ball-lever falls with thewater) until the action of the siphon has ceased in the empty ing of thecistern.

From the foregoing the combined action of the emptying-siphon andfilling-valve will be understood to be as follows: When the cistern isemptythe ball-valve is open. The siphon is covered by the cap. NVaterthen enters the cistern from the tap 15, fitted with the valve,

' omy of manufacture, it may be made separately 1 and the ball or floaton the slotted lever rises with the water until, as the cistern isfilled, it actuates the valve, closing it and shutting off the supply.If the said handle or wire 9 be now pulled or actuated, as is usual, thecover 3 is raised from the siphon, and, as hereinbefore mentioned, thesiphon consequently becomes charged with water. The handle or wire maythen be released, as the water in the cistern will continue to flowthrough the siphon until the cistern is emptied, the velocity of theflush increasing to the end of the discharge. The ball or float, beingthen in its lowest position, again actuates the valve, opening it andenabling the cistern to be again filled or charged for another flush.

As hereinbefore mentioned, it is not necessary tohold the handle orwiredown to insure the proper flushing of the closet, as the siphon isinstantly set in motion by the pulling of the handle or wire, and doesnot cease running till the cistern is emptied to the required level andthe supply is perfectly controlled bythe the improved valve arrangement.

The improved apparatus may be made to give any desired flush of watertoinsure the sufficient flushing by varying the size of cis tern 1 ofthe closet. Two gallons is a usual quantity for ordinary purposes.

Having now fully described my saidinvention and the'manner of carryingthe same into effect, I would observe, in conclusion, that Iain awarethat it hasbeen heretofore proposed to use a siphon in flushingapparatus for waterclosets, the siphon being set in action by apull-cord lifting a cap inclosing the short leg of the tube. Suchconstruction, broadly, is therefore not claimed herein; but

What I do claim, and desire to secure by Letters Patent, is-.

1. The combination, in water-waste prevent ers for use in flushingwater-closets or for other purposes, of the siphon-tube having a bend ortrap near its upper end, the closed cap or cover surrounding the openlegof the siphon, and devices for lifting said cap to start the flow ofwater, substantially as described.

2. The combination, with the cistern proat any intermediate position,substantially as described.

3. The combination, in such apparatus, with the siphon and its. guidedor vertically-depending cap or cover, as hereinbefore described, of aball or float 'lev er, slotted as hereinbefore described, andawater-supply valve or tap,

arranged'in connection with such slotted le 'ver, and beingintermittently actuated thereby, as hereinbefore described.

4. The combination of the valve, the ball or float, audits-lever,thelatter-having at its end a-slotthe extremities of which engage withpins on'said valve when the ball or float is at itshighest or lowestposition, substantially as described.
